"Today the ZFS on Linux project reached an important milestone with the official 0.6.1 release! Over two years of use by real users has convinced us ZoL is ready for wide scale deployment on everything from desktops to super computers."

This by far, is my most favourite filesystem and I've been using it on our servers for 2 years now. We have higher throughput than what we had with Ext3 (haven't benchmarked against Ext4). Maintenance wise, it's a blessing - so easy to work with. When used in combination with GlusterFS, I feel I have a solid SAN.

As for licensing, I'd really like to see all distros bundle an easy-to-use build tool for mitigating the licensing issue.
